I've been playing CS2 for a few weeks now and I've noticed the hit detection feels different compared to the older version. I'm curious about the underlying mechanics—what changes were made to how bullets register hits, especially with moving targets? Does this affect spray patterns or wall penetration in any noticeable way? Would love to hear theory explanations or tips on adapting to the new system. What do you guys think?
How does the new hit detection in Counter-Strike 2 affect aiming and movement?

The biggest tweak in CS2’s hit-detection is the shift to a server-side hit-scan that syncs a player’s hitbox to the exact point of the bullet’s travel, rather than the older “lag-compensated” snapshot we had in CS:GO. It’s similar to how Valorant handles hits: the server checks the ray at the exact moment the shot is fired, so if a target is strafing, you need to lead your crosshair a split-second earlier than before. This makes “walking” or “counter-strafing” way more important—the window where the hitbox is exposed is smaller, so landing shots on a moving opponent with a spray is tougher unless you time your fire right after their momentum stops.
Wall penetration hasn’t changed at its core, but since the hit-scan now locks onto the exact surface hit, you’ll notice a slight damage drop when shooting through multiple layers that weren’t perfectly aligned in the old system. In practice, this means favoring tighter angles and fewer “peek-through” spots, much like you’d play a game like Apex where bullet travel is more consistent but material thickness matters. Quick tip: practice the classic “stop-and-fire” timing on a moving bot—shoot right after the enemy finishes a strafe, not while they’re still moving. That habit carries over from CS:GO and will make the transition to CS2’s tighter hitboxes smoother.
